Abstract:Adverse environmental conditions limit various aspects of plant growth, productivity, and ecological distribution. For insights to the signaling pathways under low temperature, we identified 10 CBFs, 9 ICEs and 10 CORs from Aegilops-Triticum composite group as transcription factors or effector genes involved in cold stress. Conserved amino acids analysis revealed that all CBF, ICE, COR amino acid sequences all contained specific and typical functional domains. Analysis of the phylogenetic relationship among the different CBF proteins in Triticeae revealed that these CBF homologs were devided into 11 groups, and CBFs from Triticum were found in every group showing that these CBFs generated prior to the divergence of Triticum and other members of Triticeae. The evolutionary relationship among the ICE and COR proteins in Poaceae were devided into 4 groups with high multispecies specificity, respectively. Moreover, expression analysis revealed that mRNA accumulation was altered by cold treatment and the genes of three types involved in the ICE-CBF-COR signaling pathway were induced by cold stress. Together, the results enrich members of CBF, ICE, COR genes family in Triticeae, and provide a starting point for future studies on transcriptional regulatory network for improvement of chilling tolerance in crop. | |||

Abstract:Low temperatures are an abiotic stress that adversely affects the growth and production of plants. Plants\' resistance and adaptation to cold stress is dependent upon the activation of molecular networks and pathways involved in signal transduction and the regulation of cold-stress related genes. As it has numerous and complex genes, regulation factors and pathways, research on the ICE-CBF-COR signaling pathway is the most studied and detailed, which is thought to be pretty important for cold resistance of plant. In this review, we focus on function of each member, interrelation among members, influence of manipulators and repressors in ICE-CBF-COR pathway. In addition, the regulation and signal transduction about plant hormones, circadian clock and light are also discussed. The studies presented provide a detailed picture of the ICE-CBF-COR pathway. | |||
